Seems a bit harsh. Playing video games has no particular ROI (unless you want to go into creative arguments), but they cost money and take up time. Fulfillment, joy, wisdom, those are valuable even if you can't exchange them for cash.
The issue is probably rather the insane costs of education in some countries. If I had to go into debt for a big chunk of my life to study, I'm not sure I would have done it without a clear path towards paying that off.
And then lets the services like health care, prison and education be butchered for profit (that doesn't come back to the public good but feeds inequality)
The U.S. doesn’t spend most of its budget on “foreign governments”. The reason public services in the U.S. are so bad despite such high taxes is extreme inefficiency.
If we’re talking about an individual’s ROI ( as the article does ) without taking into account the overall economic benefits, then why isn’t it fair to call something free if an individual doesn’t have to pay for it themselves?
But the cost to the service user is what has bearing on the ROI calculation for those individuals. Different organisational funding systems have different interests.
I wouldn't really call university part of education outside of a few specialized vocational degrees.
It's more a life experience, part of growing up (if you have the luxury of being able to afford it) - basically a half-way house between being at home and looked after by your parents, and being out in the job market having to be responsible for yourself.
